I bought a secondhand book a few years ago and lent it to someone who has never returned it and I cannot remember the title or the author!
It was about a young man whose girlfriend/wife dies and he is such a mess after she is gone that she hangs around giving him "signs" to help him to move on with his life, I think she even somehow manages to sort out him meeting other women.
The cover picture was pretty weird with a large telephone and a cloud.
Please help! Its driving me crazy
